IMPROVEMENT IN HOLDBACKS.

Specification forming part of Letters Patent No.. 209,190, dated October 22, 1878; application iiled April 22, 17878.

To all whom it may concern:

Be it known that I, FRANK P. PFLEGHAR, of New Haven, county of NewTv Haven and State of Connecticut, have invented certain new and useful Improvements 4relatin g to Holdbacks for Carriag'es, of which the following is a specification My invention relatesto holdbacks made in two parts; and consists inthenovel construction and combination ofthe parts which are hereinafter more fully set forth and claimed.

Figure l is a view of t-he holdback attached to a section of a thill. Fig. 2 is a view ofthe front side of the part attached to the ha-rness, and Fig. 3 is a view of the opposite side.

Ilhe piece or hook A, Fig. l, is made with the base a, the under side of which is curved to fit the thill, and with the nearly semicircular upright part e, on the side of which is formed the curved ange c. Into this upright part c the slot b is made wide enough to admit the slotted end of the part B, the inner end of the slot being rounded. The outer edge of the part c, as far as the flange extends, and the iiange c are circular, the center of the circular parts being in a central line through the slot b at a distance from its inner end equal to half the width of the slot.

The part B, Fig. 2, is made with the loop o, through which the holdback-strap of the han ness passes, and with the slot m, having the lateral enlargementn. It is also made with a cavity or recess, into which the piece of rubber Fig. 3, is inserted, the rubber extending a short distance into the slot m. v

Having described the parts of my holdback,

they are put together and used in the following manner :A The part B being brought nearly in line with the slot b, the slotted end is passed into the slot b, and the part is then slight-ly pressed backward to compress the rubber and turnedto the positiony shown in Fig. Y1. The rubber prevents rattling, and the ilange c, tting into the lateral enlargement n of the slot m, prevents the separation of the parts except when the part B is in line or nearly in line with the slot b.

Having described my invention and the inode of its operation, what I claim as new,l and desire to secure by Letters Patent, is-

l. The hook A, consisting of the base a and" upright parte, having slot b, and curved flange c, in combination with piece B, having loop o, slot waits lateral enlargement n, and rubber, as shown and set forth.

2. In a holdback, the hook A, consisting of the base a and upright part e, having slot and curved iiange c, as set forth.

3. In a holdback, the piece B, having loop 0, slot m, its lateral enlargement n, and rubber x, as set forth.
